Abstract：
We present a review of the recent work related to interpreting the exotic particle X(1835) reported by BES as a NN-baryonium in the Skyrme model. There are two evidences that support this interpretation:1) There exists a classical NN-Skyrmion solution with about ～10MeV binding energy in the model; 2) The decay of this Skymion-baryonium is caused by annihilation of p-p inside X(1835) through the quantum tunneling effect, and hence the most favorable decay channels are X→η4π or X→η' 2π. These lead to reasonable interpreting the data of BES, and especially to useful prediction on the decay mode of X(1835) for the experiment.
